Assumes that the amount of tranche tokens has been locked in the DomainLocator account of the origination domain beforehand.

pub fn handle_cancel_redeem_request( pool_id: T::PoolId, tranche_id: T::TrancheId, investor: T::AccountId, currency_index: GeneralCurrencyIndexOf<T>, destination: DomainAddress ) -> DispatchResult

Cancels an redemption order. No more redeemed amount is in the system after calling this method.
